Carbon is such a versatile and perfect atom for bonding. With four valence electrons, carbon needs four more electrons to become amore stable with 8 valence electrons.This allows for carbon's ability to bond easily with a WIDEnumber of atoms.

There are many different shapes and sizes of chains a carbon atom can bond within itself. These different shapes and sizes create different substances, which is a proof for why carbon can so perfectly fit with another atom to form organic molecules.

When combined with oxygen and hydrogen, carbon can form many groups of important biological compounds including sugars, lignans, chitins, alcohols and fats. With the addition of phosphorus, carbon forms the most important molecules, DNA and RNA.
